ed as to eliminate the making of a hem at the end of the shade. Further objects and advantages oi my invention are hereinafter 19 fully set forth reference being had to theaccompanying drawing, in which,-'

Fig. l is an approx mately full size eleyation of my improved shade slat and a portion of a shade to which it is attached.

Fig. 2 is an enlargedcross sectional elevation through the slat about as on line 2-2 of Fig.1.

Fig. 3 is a fragmentary detail'view of a lower corner of a window shade and my 1m- 29 proved slat par ly broken out to reveal certain details of the fastening means.

7 Referring to thedrawing by reference letters, A designates the lower free edge portion of a window curtain or socalled shade the up- 7 per or opposite'end of which isfixed to any suitable type of shade roller (not1sl1own)well known in. the art. This free end of the shade in the usual types, is hemmed at said to its opposite upper and parallel edge (see 49 Fig. 2). In the latter and upper edge of the bar I provide a central longitudinal and nownwardly directed slit or groove G, cut to bewidest at its bottom and tapering upwardly to a comparatively thin slit in the thin edge of the slat; This slit. Gr is the shade retaining means of the slat.

i To iii; the shade in the slat about one quarter of an inch of the edge portionof the shade is folded back as best shown by the flap A in 50 Figs. 2 and 3. This flap is not sewed but shade from coming out'ot the retaining slit simply pressed back fiat upon the main shade 7 and this d'oubledpart can be slipped into the lower and wider part ofthe slat slit while i the single thickness of they shade will project 1 upwardly through the narrow opening of said slit as clearly illustratedin Fig. 2. llhe entire edge is of course folded as described and slipped into the slot from one en'd of the slat until the side edges of the shade and the ends of the bar are alined. In Fig. 1 isan eyelet in the center of the bar for the usual shade pulling cord (not shown), said eyelet being fixed in the bar below slit-G. r

' To positively prevent the folded edge of the I further provide'simple holding means con sisting of a number of common pins P of the household variety. These'pins are inserted longitudinally in the crease made flap A as best shown inFig. 3'. This provides an eiiective locking means for the shade because the latter is thickened at the creaseand the heads of the pins spread the goods to efiective- 1y. engagethe adjacent walls of the slit G- and also prevent accidental end slipping of the 5 shade therein. 1 V

Obviously it is notnecessary to limit my improved shade slat to wooden bar construc- .tion as it could readily be made of formed sheet metal with a slit corresponding to slit G.

t wouldalso be possible to make said barof cast rubber or other material embodying the same improvements.

I claim: l I

A shade slat for the movable free end of a window shade, said slat comprising an elongated barprovided with a longitudinal slit throughout its length and said slit being widest atits bottom and tapered to a narrow opening at the exterior of the slat, and'means for retalning said end part of the shade in'said slit, said means consisting ofa flap formed by folding the free edge of said shade, and a number of headed pins inserted longitudinally in the shade material at the crease of said a fold, substantially as shown and described;

Intestimony whereof I affix my signature.
